  • A credibilistic approach to assumption-based truth maintenance 
    Shen, Qiang; Zhao, Ruiqing (2010-08-30)
    This paper presents an extension of the assumption-based truth maintenance system (ATMS), called “credibilistic ATMS,” which has the capability to cope with uncertain justifications and assumptions. Such justifications and ...
  • Modelling random fuzzy renewal reward processes 
    Shen, Qiang; Zhao, Ruiqing; Tang, Wansheng (2008-10)
    This short paper discusses the modeling of random fuzzy renewal reward processes in which the interarrival times and rewards are represented by nonnegative random fuzzy variables. Based on random fuzzy theory, a random ...
  • Random Fuzzy Alternating Renewal Processes 
    Zhao, Ruiqing; Shen, Qiang; Tang, Wansheng (2009)
    Random fuzzy theory offers an appropriate mechanism to model random fuzzy phenomena, with a random fuzzy variable defined as a function from a credibility space to a collection of random variables. Based on this theory, ...
  • Risk assessment of serious crime with fuzzy random theory 
    Shen, Qiang; Zhao, Ruiqing (2010-11-15)
    This paper presents a novel approach for assessing the potential risk of serious crime events (e.g. terrorist attack). The modelling and assessment of such risk is carried out under uncertain circumstances because of both ...
  • Towards Fuzzy Compositional Modelling 
    Shen, Qiang; Zhao, Ruiqing; Fu, Xin (2007-07-23)
    Compositional Modelling (CM) has been applied to synthesize automatically plausible scenarios in many problem domains with promising results. However, it is assumed that the generic and reusable model fragments within the ...
